V4L/DVB (7170): soc_camera V4L2 driver for directly-connected SoC-based cameras

This driver provides an interface between platform-specific camera
busses and camera devices. It should be used if the camera is connected
not over a "proper" bus like PCI or USB, but over a special bus, like,
for example, the Quick Capture interface on PXA270 SoCs. Later it should
also be used for i.MX31 SoCs from Freescale.  It can handle multiple
cameras and / or multiple busses, which can be used, e.g., in
stereo-vision applications.
